Question

In a basic sine curve, where can the zeros NOT be found?

Answer 1

Answer: Option 'C' is correct.

Step-by-step explanation:

Since we know that

$f(x)=\sin x$

It is an odd function.

It has a period of 2π because the sine wave repeats after every 2π units.

It value lies between -1 and 1.

And we know that

$\sin 0^\circ=0^\circ$

And 0 occurs exactly middle of -1 and 1.

So, the zeroes can be found in the middle, beginning and at the end.

But at maximum point, there will be no zero.

As when it attains its maximum point, it won't touch x-axis.

Hence, Option 'C' is correct.
